[PATCH 0/4] Support registering specific reset handler

[Gavin Shan]

VFIO PCI infrastructure depends on pci_reset_function() to do reset on
PCI devices so that they would be in clean state when host or guest grabs
them. Unfortunately, the function doesn't work (or not well) on some PCI
devices that require EEH PE reset.

The patchset extends the quirk for PCI device speicific reset methods to
allow dynamically registration. With it, we can translate reset requests
for those special PCI devcies to EEH PE reset, which is only avaialble on
64-bits PowerPC platforms.

Gavin Shan (4):
  PCI: Rename struct pci_dev_reset_methods
  PCI: Introduce list for device reset methods
  PCI: Allow registering reset method
  powerpc/powernv: Register PCI dev specific reset handlers
